Well if it does cause such effects then it is surely worth a
try to disable it.

udev and hald are the natural enemies of burn programs.
We compete for the same hardware and the OS normally does not
care about arbitrating.
Nevertheless, i would have expected that the block device
driver gets more respect by udev.

It advises to try:
  udisks --inhibit-polling /dev/dvd
or
  udisks --inhibit-polling /dev/sr0

Do you have more information about udev causing read-only optical
media ?


Have a nice day :)
